   Aims to fix #23589. Host and port validation on torcontrol, same logic is being used on the other flags which need this validation as well.

   This is my first PR for bitcoin core and came across this good first issue, continued on already existing code for this issue.

   Took some inspiration from this comment

2. Ensure valid network address in `-torcontrol`

   - Returns error at init if `-torcontrol` is not a valid host:port combo.
   - `StartTorControl` returns a `bool`, and has a return parameter `error`
   where a suitable message is set at failure.
   
   Fixes #23589

3. util: Adds `network`, network address validation

   This utility implements the function `hasValidHostPort`, which conducts
   a sanity check for a valid host:port combination in a string.
   This can be used for rejection of invalid option strings. Rules for
   a valid hostname are: not empty and no spaces, for port: not empty
   and within `uint16` bounds.
